Adjust for Comfort: Adjust the length of the acoustic tube and the position of the PTT unit for maximum comfort and discretion.

Operating Instructions

Receiving Audio: Once connected, audio from your two-way radio will be transmitted directly through the acoustic tube earpiece. Ensure your radio's volume is set to an appropriate level for clear listening.
Transmitting Audio (Push-To-Talk - PTT): To speak, press and hold the PTT button located on the lapel microphone unit. Speak clearly into the microphone. Release the PTT button when you have finished speaking to return to receive mode.
Microphone Placement: For optimal voice clarity, ensure the microphone is positioned close to your mouth and not obstructed by clothing.

Maintenance and Care

Cleaning:
- Wipe the earpiece, acoustic tube, and PTT unit with a soft, damp cloth.
- Do not use harsh chemicals or abrasive cleaners.
- The silicone earbud can be removed and cleaned with mild soap and water, then thoroughly dried before reattaching.
Storage: Store the earpiece in a clean, dry place away from direct sunlight and extreme temperatures. Avoid tangling the cable.
Handling: While the cable is Kevlar reinforced for durability, avoid excessive pulling or bending of the cable, especially near the connectors, to prevent damage.
